Nuclear Medicine
Managing radioactive wastewater at the source.
For departments handling high-dose radionuclide therapies.
The challenge
Growing therapy demand is putting pressure on existing infrastructure.
Nuclear medicine departments are treating more patients than ever. But existing wastewater systems were not designed to handle this scale. Decay tanks require space, investment and long processing times, while increasing volumes strain capacity and limit growth.
As regulatory pressure rises, hospitals are forced to rethink how radioactive wastewater is managed — without compromising care delivery.
Limited tank capacity
Existing infrastructure struggles to keep up with increasing patient volumes.
Space & cost constraints
Expanding tank systems requires significant investment and physical space.
Inefficient downstream handling
Dilution and storage do not solve contamination at the source.
The Zereau approach
Filtering at the source instead of managing downstream.
Zereau systems capture radioactive contaminants directly at the point of origin — before they enter the wastewater system. By filtering at the source, hospitals reduce pressure on decay tanks, increase operational flexibility and create immediate capacity for growth.
This approach integrates seamlessly into existing workflows, without requiring major infrastructure changes.
System configurations
Flexible system setups tailored to different clinical environments and infrastructure constraints.
RadiCatch Toilet Filter System
Where patients receive radionuclide therapies, excretions contain high concentrations of radioactive contaminants. This system filters wastewater directly at the source, preventing contamination from entering the hospital infrastructure.
- Installed in patient bathrooms
- Reduces tank dependency
- Requires minimal infrastructure changes
Ideal for patient-room installations with high radionuclide excretion loads
RadiCatch FilterBOX
Designed for therapy rooms and controlled clinical environments, the FilterBOX captures radioactive contaminants directly at the point of disposal. By integrating with existing wastewater connections, it enables immediate filtration without disrupting clinical workflows.
- Installed in therapy or treatment rooms
- Connects to existing drainage systems
- Reduces load on central tank infrastructure
Ideal for high-dose I-131 and Lu-177 applications
RadiCatch XL System
For hospitals with higher patient volumes or centralized infrastructure, the XL System provides scalable filtration capacity at key wastewater points. It enables facilities to manage peak loads efficiently while maintaining compliance and operational continuity.
- Designed for high-capacity environments
- Supports centralized filtration setups
- Scales with growing therapy demand
Suitable for large departments and multi-room setups

EANM 2026: Zereau at Booth 321 – hall X3. Is Our Infrastructure Ready for the Growth of Nuclear Medicine?
Next week, the nuclear medicine community comes together in Vienna for EANM’26. Radioligand therapy is expanding. New radiopharmaceuticals are moving through clinical development. Alpha therapies are gaining momentum. Patient access is increasing, and hospitals across Europe are preparing for further growth.

What hospitals say:
"The Zereau RadiCatch FilterBOX is installed in one of our therapy rooms and connected to our decay tanks. By filtering the excretions of high-dose I-131 patients, we freed enough tank capacity to expand our therapy program — increasing treatments from 700 to 900 per year."

Impact at the source
Zereau systems deliver measurable environmental and operational impact.
>99,9% removal
Removal at the source, where concentrations are highest.
-70% water
Less water to treat means lower energy use and reduced operational costs.
100% circular potential
Captured residues enable recovery and reuse of valuable materials.
0 downstream issues
Prevent contamination before it reaches municipal wastewater systems.
